Re : Asco found on Fraxinus twig
Hi Robin,
by chance I just came across a post on Twitter 5 minutes ago where Mark Powell showed Unguiculariopsis thallophila on Lecanora hybocarpa. This seems to match your collection rather well, in particular since your brown ascomycete seems to be on some lichen, so you might compare with it.

Hi,
Yes of course, I have seen it several times before. Was completely in other thoughts.

Re : Asco found on Fraxinus twig
I agree. There is a wide range in the ascospore width in the literature: 6-10 x 2-4 µm. What I studied (3 samples with drawings) has spores around 6-8 x 2.3-2.7 µm. Your spores look distinctly broader than mine, though of the same length.
More details about the hairs would helpful, they have usually narrowed and curved apices.
